The 1-channel IM43-13-R trip amplifier 0/4…
20 mA currents or 0/2…10 V voltages for
overshoot and undershoot of limit values.
The three limit values are set via the lateral rotary coding switches.
Additionally, 18 V (with max. 35 mA) are provided for transmitters or sensors.

The green LED indicates operational readiness. Three yellow LEDs indicate the switching status of the corresponding output.
The output mode of the relays and the hysteresis are set via DIP switches.
